When 538 had the Dems at 34% chance to gain majority in the senate they had:
The Dem probably flipping NV an AZ and Heitkamp probably keeping the Dem seat in ND.
If all of their lead picks held, the Dems would take control.
Now they have Heitkamp behind in ND.
They also have Cruz easily beating Beto in TX but I don’t know about that.
And TN could still flip from red to blue.
The whole control of the senate may come down to Heitkamp vs Cramer in North Dakota.
Heitkamp voted to confirm Gorsuch, going against her fellow Democrats.
Now there is a vote on Kavanaugh. She expected to vote no and is in a red state. Her no vote could cost her the election and Dem control of the senate.
A yes for her may put Kavanaugh on the bench but get her the win and Dems control of the senate.
I think the senate is still up for grabs and we have no idea what first time or irregular voters may show up.
